RHIZOCTONIA Meaning and
Definition
-
Rhizoctonia is a genus of filamentous fungi belonging to the family Ceratobasidiaceae. It is a plant pathogenic fungus that causes diseases in a wide range of crops, including cereals, vegetables, and ornamental plants. This genus is commonly known as a root rot pathogen as it primarily attacks the roots of plants, leading to significant damage and yield loss.
The name "Rhizoctonia" is derived from the Greek words "rhiza" meaning "root" and "ktonos" meaning "killing," emphasizing its destructive effect on plant roots. Rhizoctonia is characterized by its filamentous mycelium, which grows extensively within the soil and aggressively invades the root system of susceptible plants.
The symptoms of Rhizoctonia-infected plants vary depending on the host plant and environmental conditions but often include wilting, stunted growth, root decay, and damping-off of seedlings. The pathogen can survive in soil, plant debris, or on the roots of infected plants, allowing for its persistence and easy transmission to new hosts.
Controlling Rhizoctonia is challenging due to its ability to form long-lasting survival structures called sclerotia, which enable it to survive adverse conditions. Cultural practices such as crop rotation, sanitation, and avoidance of waterlogged or over-fertilized soils can help reduce the incidence of Rhizoctonia infections. In severe cases, chemical fungicides may be used to manage the disease.
Overall, Rhizoctonia is a significant plant pathogen that poses a threat to agricultural productivity. Understanding its biology, disease symptoms, and management strategies is essential for effective control and prevention of its impact on crop production.

Etymology of RHIZOCTONIA
The word "Rhizoctonia" is derived from Greek and Latin roots.
- The Greek word "rhiza" means "root".
- The Latin word "octo" means "eight", referring to the fungus's eight-spored cells.
- The Latin suffix "-ia" is commonly used in the classification of fungi, specifically indicating a genus.
Therefore, "Rhizoctonia" can be understood as "root" + "eight" + "-ia", denoting a genus of fungi that primarily affects plant roots.
